Question 321991: using the five-step problem-solving process
Express the answer in scientific notation to two decimals places unless requested otherwise
If the speed of light is 3.00 ×10^8m/sec, how long does it take light to travel 2.29 × 10^11 m, the distance from the sun to Mars? Round to one decimal place
Can someone walk me through this one

Rate*Time=Distance
Rate is equivalent to speed.
R%2At=D

Rate is equivalent to speed.
t=D%2FR=%282.29%2A10%5E%2811%29%29%2F%283%2A10%5E%288%29%29
t=763.3seconds to one decimal place,
t=763.3seconds to two decimal places
or in scientific notation,
t=7.6x10%5E%282%29seconds or
t=7.63x10%5E%282%29seconds
